Accelsior 4M2
PCIe NVMe M.2 SSD Adapter Card

High-Performance PCIe NVMe M.2 SSD Adapter Card

Build The Fastest SSD Available

When OWC launched its first Solid State Drive in 2010, it was engineered to deliver the same attribute formula that Mac and PC users expected from OWC external storage solutions:

High performance + high reliability + affordable price = The OWC Difference

Nearly a decade later, our commitment to that winning formula remains steadfast as we push the boundaries of leading-edge SSD development with the Accelsior 4M2. It’s ideal for uncompromised, data intensive, high bandwidth needs like large format video editing, VR/AR/MR environments, high transactional and complex calculation applications, and extreme gaming.

Accelsior 4M2 houses up to four NVMe M.2 SSDs under a finned heat sink cover that provides silent, throttle-free cooling. When tested with OWC Aura P12 Pro NVMe M.2 SSDs, Accelsior 4M2 delivers over 6,000MB/s real-world speed with the highest reliability possible.

Highly Versatile with Mobile Possibilities

Whether you have the Mac Pro 2019, a Mac Pro 2012 or 2010, or PC tower, Accelsior 4M2 can go to work for you. As a half-length x8/x16 compatible card, this game-changer offers the versatility you need, so you’re not tied to one PCIe slot size or limited by a space-confined computer case.

You can also enjoy the performance boosting benefits of Accelsior 4M2 with your Thunderbolt 3-equipped notebook computer, iMac workstation, or slot filled gaming rig. It’s Plug and Play easy with a PCIe expansion chassis like the OWC Mercury Helios 3S.
